I refer specifically to tandoor ovens, purchased for use at home. How essential are they for producing BIR flavours when making tikka and naan bread? I'm not convinced and it reminds me of my interest in hi-fi a few decades ago. The hi-fi magazines would have you believe it was essential to purchase loudspeaker and phono type cables which were hyper expensive due to the materials they claimed were used for better conductivity and sonic excellence. I now reckon it was all hype, aimed at getting gullible people to spend more money.
Tikka can be cooked to perfection using a domesic grill or barbecue.
Naan bread can be cooked perfectly well using the inverted pan method.
Who needs a bulky tandoor, unless you're primarily interested in the theatrics and to impress guests?
Also, aren't there one or two people on here who are linked to tandoor oven suppliers?
